Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 8,936,135, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 8,936,135 | |
| -1 | -8,936,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,936,135.
Example:
1 x 8,936,135 = 8,936,135
and
-1 x -8,936,135 = 8,936,135
Notice both answers equal 8,936,135
With that explanation out of the way, let's continue. Next, we take the number 8,936,135 and divide it by 2:
8,936,135 ÷ 2 = 4,468,067.5
If the quotient is a whole number, then 2 and 4,468,067.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 8,936,135 | |
| -1 | -8,936,135 |
Now, we try dividing 8,936,135 by 3:
8,936,135 ÷ 3 = 2,978,711.6667
If the quotient is a whole number, then 3 and 2,978,711.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 8,936,135 | |
| -1 | -8,936,135 |
Let's try dividing by 4:
8,936,135 ÷ 4 = 2,234,033.75
If the quotient is a whole number, then 4 and 2,234,033.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 8,936,135 | |
| -1 | 8,936,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 8,087 | 40,435 | 105,131 | 137,479 | 525,655 | 687,395 | 1,787,227 | 8,936,135 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -8,087 | -40,435 | -105,131 | -137,479 | -525,655 | -687,395 | -1,787,227 | -8,936,135 |
